Click And Pop Sounds On Preset Change!!!

Hello Everyone
Just Playing Around With Shape FX Module, And Found Out When I Save And Reload A Preset, I Get Some Nasty Click And Pops Becuase OF Shape FX
Any One Face With Same Problem ???
And How I Can Solve It

Actually The Problem Is Because Of The Bias Knobs.
I Used Them In A Couple Of My Presets , And When I Search throw The Presets As Soon As I Reach To Them The Pops And Click Appear.
Just A Small Click After Pressing The Next Or Prev Buttons.

I Think The Solution Is To Turn Down The Gain For A Few Milliseconds And Go Back To Zero.
But Don't Know How To Achieve That
